Flashcards in Vision I-III Deck (3)
Monocular deprivation in kittens
After, animal couldn't see out of the eye that was shut. "Use it or lose it" hypothesis
Cortex didn't respond to stimulation of contralateral eye
Cortex loses connections to the deprived eye
Connections are lost for good
Binocular deprivation in kittens
DOESN'T produce a nearly silent cortex, as might be expected from the results of monocular deprivation
Instead, primary visual cortex was for the most part normal
The cats, however, were behaviorally blind, which means that higher order visual cells were completely disrupted.
Hypothesis: Competition - active suppression by the active eye - that occurs between converging inputs from each eye in the cortex.
More complicated than "use it or lose it"
